Studies on the Development of Mango (Mangifera indica L.) Fruit
Mango varieties ''Irwin'' , ''Hadan'' and ''Local'' were used to study the physical , morphological , anatomacal and chemical changes in growth and development of mango fruits. The results indicated growth curves of fresh weight 、volume、length、width 、thickness of fruits and seeds showed typical single sigmoid patterns. It take 120 days for ''Irwin'' ,''Haden'' and 100 days for ''Local'' fruits to reach full size .The color of peels in ''Irwin'' and ''Haden'' appeared orange with red,and ''Local'' was turned to light yellow when it became maturity. The souble solids of juice increased following fruit develpoment.Specific gravity and dry matter content of fruit showed a type curve.The starch increased follow with endocarp harden. Cell layers and size in pulp were investigated by section and microgreph technology.Results indicated the period of cell division in ''Irwin''、''Local ''、''Haden'' mango were from full bloom to the initial stage of rapidly growth in fruit.The period of cell division in ''Irwin'' and ''Haden'' terminated in 76 days after full bloom and ''Local'' terminated in 62 days after full bloom.The cell size became to enlargement and hypertrophy after that time as mentioned above.The cell layers of the middle part were four times for ''Irwin'' ,''Haden'' and six times for ''Local'' than the top and bottom part of fruit .In the meanwhile ,the cells of middle layers in pulp was the earliest hypertrophy and inner layer was the second,final was out layer cells in pulp.The layers and size of cell in pulp were related to the variety in fruit.The cell layer in ''Irwin'' and ''Haden'' was more than ''Local'' and cell size was also larger than ''Local''.
